W'ELllr-CASING.

all whom'itmuy concern:

Be.it lrn0wn that i, BARENT a citizen of the. United States, and a. resident of Grand Ridge, in the county of Lasalle and State of Illinois, have invented a new and-Improved Well-Casing, of which the following is a full; clear, andexact descrip tion.

My invention relates generally to well casings and more particularly it is directed to an improved means for holding together the units described and claimed in Letters Patent No. 1,001,523, granted to me August 22, 1911. v

The object of my invention is toprovide a new and improved means for securing in operative position a number of the well casing units set-forth in the above application,

the said securing means being preferably vertically extending rods which may occupy a variety of positions with respect. to the said units. i v I Reference is to be had -to the accompanying drawings, forming-a part of this specifierence denote correspondingparts in an the views,iand-inwhich-' v 1 Figure 1' is a sectional view of a well con.- taining a casing made up of my units; Fig. 2 is a perspective view of a, number of units secured together in one manner; Fig. 3 is a vertical sectional View thereof; Fig. 4 is a horizontal sectional view of Fig. 2; Fig. 5 is a perspective view of. one of the units; Fig. 6 is a horizontal sectional view showing a slightly diflerent manner of connecting the units.

.' The unit comprises the concentric cylin drical members 1 2, the former being of less diameter than the latter, and the two members being secured together by a continuous portion 3, preferably integral therewith, this portion being providedat a suitable number of points wit-h openings- 4 of any suitable shape. The smaller cylindrical member 1 is provided with any desirable number-of perforations 5,1suitably spaced there-around and the outer cylindrical memher 2 is also provided with a number of perforations similarly spaced,. it being noted that the perforations 5 and 6 together with the opening4lie in-the same vertical plane.

The units are designed to be positioned one above the other'and inserted in position withina well, the/units forming a. casing therefor, themeans for holdingthem one Specification of Letters Patent. Patented Nov. 21, Application filed July 11,

. above the other being preferably anumber of vertically extending rods. Each of the rods 10 is provided with a series of perforations 11 suitably spaced apart, the distance between these perforations being the dis tance it is desired to maintain between the perforations 6 on the successive units so that by placing one of these in each of the openings 4 in the intermediate portion 3 of the series of units the same may be secured on the I'Od'bf, any suitable means engaging the perforations, 6 of one unit-and one of the perforations Him the rod together with a perforation 5 in the upper cylindrical part devices engaging in these perforations may be that which is best suited for the purpose,

and nuts or any'equivalentmeans. In Fig. 6.1 have shown a modified positioning ofthese rods, the arrangement shown having .two series of rods, one series 10 engaging the perforations 6 in t-he succeeding units while. the otherseries 10 engages the perforations 5 in the upper portion of the succeeding units. Either arrangement is adapted to hold the units securely together in position for use, it being obvious that one ticular use than the other, the size ofthe theunits increase in diameter double securmaterial of these rods may be what is best suited to the purpose and most desirable both from .a standpoint of efficiency and also of cost, changes" in the material and size'being within the spirit of the appended claims.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent to form a well casing, together with means extending vertically of the well andengagmg each ,of the units whereby they are suitably spaced one from the other.

2. A plurality of succeeding unitscomprising a smaller cylindrical part, a larger concentric cylindrical part means connecting the parts, together with a plurality of ment with the succeeding units whereby they are suitably spaced.

3. .A well casing made up of, 'a' number of succeeding units of similar construction, to?

getlicr with a plurality of rods engagin the of the next succeeding unit. The'means'orarrangement maybe more suited to a par units infiuencing'the arrangement, since as which may takethe form of rivets or bolts in'g means may be desirable. A Of course the f 1'. Aplurality of succeeding units adapted I vertically extending members in engage- 7 succeeding units for spacing them one from the other, the said rods and units forming a single structure.

at. A well casing made up of a plurality of units, rods engaging the units, the rods being secured in order to properly space one unit from each succeeding one.

A well casing comprising a plurality of units, each unit being provided with a plurality of perforations, a plurality of rods, ach rod containing a plurality of perforations, the units being positioned on the said rods, together with means engaging each succeeding unit and the rod for holding the parts together and one unit properly spaced from the succeeding unit.

6. A well casing made up of a plurality of units. each unit con'iprising an upper cylindrical portion and a largerconcentric cylindrical lower portion, the portions being connected together, a plurality of openings in each unit. together with rods engaging the openings in succeeding units, there being suitable means engaging the rods and adjacent units in order to secure the parts to gethcr and to hold them properly spaced with respect to each other.

'7. A well casing made up of a plurality of units, each unit comprising a cylindrical upper part and a larger concentric lower part with a connecting portion between them, the connecting portion being provided with a. plurality of openings, a plurality of rods engaging the openings in each unit, and rivets engaging the upper part of one unit and a rod and the lower part of the succeeding unit, whereby the units and the rods are held together in a single structure with the proper space between the units. v

S. A well casing comprising a plurality of units of similar construction, together with means engaging each of the units for spacing them one from the other.

In testimony whereof I have signed my name to this specification the presence of two subscribing witnesses.
